Ronny Yu Yan-tai, who would be later known for his 1993 classic Bride With White Hair, spins this atmospheric horror flick set in 1922 Xiang Xi. When an iterate musician runs afoul of the local warlord, the potentate has him killed and hires a band of opium runners to dispatch with the body. While travelling through a swamp, the corpse falls into a sulfuric spring. Not wanting to deal with the stink of the spring, the lackeys decide to leave the body there. The combination of bog juice and sulfur revives the dead man, sending him on a vengeful killing spree. After knocking off a bunch of pigs, he kills everyone related to his death. The culprits retaliate with Taoist charms, virgin urine, and a host of other tricks of the zombie-killing trade.
